Specification of Letters Patent.

Patented July 13, 1915.

Application filed October 13, 1914. Serial No. 866,443.

To all whom it may concern:

Be it known that I, CHARLES C. BELoHER, a citizen of the United States of America, and a resident of Whigham, county of Grady and State of Georgia, have invented certain new and useful Improvements in Hydrometers, of which the following is a full and clear specification, reference being had to the accompanying drawings, in which- Figure l is a vertical section, partly in side elevation; and Fig. 2 is a plan view of a simple embodiment of my invention.

This invention has special reference to that class of hydrometers especially adapted for indicating the density of cane sugar syrup as it runs in a small and practically continuous stream from the evaporating pans, and the object of this invention is to provide an extremely simple device which will be sensitive to slight fluctuations in the density, even when the stream of liquid from the pans is running very irregularly and in a small quantity.

A further object is to enable the device to be read by the attendant at a considerable distance from the device, so that the attendant may, without inconvenience, observe the indicated variance in the density of the syrup, as more fully hereinafter set forth.

In the drawing, a; designates a small shallow trough leading from the evaporating apparatus, not shown, and b a depression or sink in this trough adapted to contain a small quantity of the liquid as it passes through the trough. This sink is provided with a vertical partition 0 whose lower end terminates near the bottom of the sink, thus compelling allthe liquid that passes through the trough to empty into the sink and flow down underneath the partition. On the back of the partition plate is removably fastened a vertically slidable hydrometer rod d of the usual material, adapted for the sugar business. The lower end of this rod is suspended in the sink close to the partition 0, and the lower edge of the partition 0 is extended backwardly to form a deflector e which insures the protection of the hydrometer rod against being lifted or swung about by the upflowing liquid. This rod is detachably suspended at its upper end to the shorter end of a pointer 7 which is pivotally supported at g and whose longer arm cooperates with an enlarged scale 71.. The pivot g, as well as the removable pivot pin 71 which detachably suspends rod d on the indicator lever f, are constructed so as to reduce friction to a minimum. The indicator lever f is so arranged as to exactly balance on the pivot y when disconnected from the hydrometer rod, so that the connection of the hydrometer rod to this lever has no effect upon the sensitiveness of the hydrometer. The hydrometer rod itself may be provided with a scale similar to scale it if desired. To removably support the rod d, I employ two clips j which are adapted to be sprung open to admit the rod and to remove the same. This hydrometer rod is made removable in order that other rods suitable to particular work may be substituted from time to time.

It will be observed that I provide an extremely simple, inexpensive indicating'device which will be within the means of a lar e class of small syrup makers. It will also e observed that by making the hydrometer rod removable the apparatus may be readily adapted for different kinds of syrup. It will be seen also that my apparatus is operable with but a small quantity of syrup, thus adapting it for effectual use with small evaporating plants, where the flow is not only slight, but is extremely irregular, not only as to quantity but as to density.

Having thus described my invention, what I claim is:

In an apparatus of the class set forth, the combination of a trough provided with a depression or sink, a partition extending to near the bottom of the sink and provided at its lower edge with a backwardly turned deflector, a hydrometer rod slidably mounted on the rear face of the partition, an indi cator lever connected to the upper end of said rod, and a scale operating with said lever, said rod being located vertically above the deflector, where the liquid is stillest.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

CHARLES CLIFFORD BELCHER.
